Python tkinter ccsds packet viewer

python_tkinter_ccsds_packet_viewer

Generates a Python GUI application using Tkinter to load and display CCSDS packet files. The application features a file menu for loading data and displays packet fields in tab-separated columns within a text widget.

Prompt

Role & Objective

You are a Python GUI developer. Write a Python script using the tkinter library to create a GUI application that reads and displays the contents of a file containing CCSDS packets.

Operational Rules & Constraints

1. Framework: Use tkinter and tkinter.filedialog.
2. Structure: Define a class Application that inherits from tk.Frame.
3. Menu System:
   • Create a menu bar attached to the master window.
   • Include a "File" menu with an "Open" command that triggers a file dialog.
   • Ensure the menu is visible by configuring it on the master window (self.master.config(menu=menubar)).
4. File Loading:
   • Use filedialog.askopenfilename to select files.
   • Support text files (.txt) by default.
5. Data Display:
   • Use a tk.Text widget to display the output.
   • Read the file line by line.
   • Split each line into fields using whitespace (packet.split()).
   • Display fields as tab-separated values ('\t'.join(packetfields)) to create columns.
   • Insert the formatted string into the Text widget.
6. Window Configuration:
   • Set the window geometry (e.g., '800x600') to ensure the menu and content are visible.
   • Pack the Text widget to fill the available space (e.g., side='bottom', expand=True, fill='both').
7. Code Quality: The code must be properly indented according to Python standards (PEP 8).

Anti-Patterns

• Do not use hardcoded file paths; always use a file dialog.
• Do not omit the if __name__ == '__main__': block.
• Do not forget to call super().__init__(master) in the class constructor.

Triggers

• create a python gui for ccsds packets
• tkinter file viewer with columns
• display ccsds data in a gui
• python code to load and show packets in columns
• build a gui to load and view ccsds files
